Description

The Spiny everlasting is a woody perennial shrub with spines at branch ends, covered in short white hair. It bears oblong, bumpy fruit.

Spiny everlasting was presumed extinct in 1992, having suffered habitat loss from clearance for winter crops, but various colonies of it have been found around Laura, near the Spencer Gulf.

Homonym

In 1883, William Mitten used the same name, Acanthocladium, to refer to a group of mosses, now in the family Sematophyllaceae.[7] Several dozen species of mosses were described and place in this genus before it was realized that Mittenn's name represented an illegitimate homonym.[8] The moss genus has since been renamed Wijkia H.A. Crum.[9][10]
